i pecially adapted for burning of hydrocarbon oils.

It is the object and purpose of my invention to provide a burner in which a perfect and complete combustion of liquid fuel such as kerosene oil or the like may be obtained and also one in which there is not required any initial generation of the oil into a gas before perfect combustion. can take place, the burner being operable inmediately without previous heating of parts for the generation of a gas from the liquid fuel supplied thereto.

Various other objects and purposes together with novel' construction for attaining the same, especiallyva construction by means of which an open air burner is attained which may be used without danger of the burner becoming extinguished irrespective of atmospheric conditions under which the burner is used will be apparent as understanding of the invention is had, reference being had to the accompanying drawing, in which:

Figure 1 is a side elevation of a complete burner. Fig. 2 is a vertical transverse seetion taken centrally of the construction shown in Fig. 1; and Fig. 3 is a partial sectional and side elevation of the principal elements of the burner construction.

Like reference characters refer to like parts throughout the several views of the drawing.

This burner is adapted to consume liquid fuel such as kerosene oil or the like and the oil is supplied to the burner through a pipe 1, the amount thereof being controlled by a valve 2 of ordinary construction interposed in the length of the pipe and operable by the hand wheel 3 in the usual manner. The oil may be in any suitable receptacle under pressure and passes from the pipe 1 to a member 4 which has a reduced passage therethrough and which is threaded into one end of a T-coupling 5,v there being a tapering extension 6 to the member 4 which passes practically through the coupling. Steam is supplied in the use of this burner, entering through a pipe 7 into the T-coupling, the amount thereof being controlled by a valve 8 operated by a hand wheel 9 in the usual manner, said steam entering around the tapered extension 6 of the member 4 and passing through a short coupling l0 around the end of said extension. It is ap- Y parent that the steam mixes with the oil raising the temperature thereof and carrying it in nely divided or atomized stateV through the coupling 10 and into an elongated member 13, this member being provided with a passageway which extends the entire length thereof and which increases inv size as it gets farther awayrfrom the coupling 10.

Adjacent its outer end member 11 is formed with Yan enlargement 13, the extreme end of said member being threaded so that the burner head 14 may be detachably secured thereto, in its attachment abutting against the enlarged member 13 as shown. A plurality of openings 15 are formed through the sides of the member 11 and similarly the plurality of openings 16 are made in the burner head 14. A sleeve 17 is threaded on to the member 11 as shown, abutting against the enlargement 13, this sleeve being of use only as a handle for manually controlling the position of the burner, its free end being spaced from the member 11 a sufficient distance to permit all of the air needed to go through openings 15.

In operation the oil under pressure passing through the extension 6 of member 4 is carried by the steam in finely divided state to the member 11 and in the large passageway the steam expands, there being created in this manner a suction to draw air through openings 15 which mixing with the combined oil and steam makes a combustible mixture that may be lighted and which will burn outward from the point 18 at the end of the member 11. The flame from the burner accordingly reaches from this point outward and any additional air that is needed for perfect combustion is drawn through the openings 16. The heat from the steam aids in the practical atomizing of the fuel and the air supplied through openings 15 is sufficient to provide a combustible mixture and one which will always burn from the point 18 outward. Accordingly when once lighted the burner will not to be extinguished by gusts of wind or the like when it is used in the open air as all of the flame is not beyond the burner head lat but the head itself is lled with flame which is protected against extinguishment.

From the foregoing it will be apparent that I have provided a simple and easily constructed burner for hydrocarbon oils such as kerosene, crude petroleum and the like and in actual practice this burner has proved to be especially efficient for burning even the poorest grade of kerosene without trace of smoke and' under trying atmosf pheric conditions. Furthermore this burner requires but very little steam in its operation, in fact too large a supply of Steam may work against its successful operation.

I claim z- 1. In a device of the character described. a member having a tapered extension and with a passage extending therethrough, a

coupling through which said member is inserted, means to carry liquid fuel to said member, means to introduce steam r the like into the coupling around the extension, an elongated member connected to the coupling into which the combined steam and uel is passed, said member having an elongated passageway therethrough, the cross-section of which increases outwardly away from the coupling, and also having a plurality of openings through the walls of the member for the entrance of air, and an enlarged hollow head having a plurality of openings through its walls secured at the end of the elongated member, substantially as described.

2. In a device of the character described, a hollow burner head provided with a plurality or" openings through its walls, an elongated member to one end of which the burner head is secured, said member having a longitudinal passageway of comparatively large cross-section and with a plurality of openings therethrough for the entrance of air to the passageway, said cross section progressively diminishing in area away from the burner head, and means for introducing a limited amount of liquid fuel and steam into the passageway in said elongated member, substantially as described.

In testimony whereof I aiiiX my signature.
